Abstract


Introduction

Colorectal cancer (crc) remains a major public health problem worldwide. regarding cyclooxygenase -2 (cox- 2) overexpression in most crc tissue and is associated with processes such as angiogenesis, inhibition of apoptosis, and metastasis of colon cancer cells, we have examined the effects of lgk974 and aspirin drugs on cox- 2 in sw742 colorectal cancer cells compared to oxaliplatin drug in vitro.

Methods

Mtt (methyl tetrazolium assay) colorimetric assay was used to investigate cell viability in the presence of drugs. real time pcr was used for the measurement of the effect of the drugs in cox-2 gene expression. statistical analysis was determined by one-way anova and tukey multiple range analysis (spss 19.0 software (p <0.05).

Results

The analysis of the results indicated that treatment with lgk974 and aspirin drugs inhibited the growth of sw742 cancer cells. also, in this cell line, treatment with ic50 concentration of lgk974 and aspirin decreased expression of the cox-2 gene by 1.52 and 1.93 log fold change respectively.

Conclusion

We conclude that lgk974 and aspirin drugs cause inhibition of growth and decreases expression of the cox-2 gene in the sw742 cancer cells in vitro. so, these drugs might serve as a new strategy for the treatment of crc.
